What is mod 12 system?

The mod 12 system, also known as modulo 12, is a mathematical framework where numbers wrap around after reaching 12. This means that any integer can be expressed as its remainder when divided by 12. For example, 15 mod 12 equals 3, since 15 divided by 12 leaves a remainder of 3. This system is commonly used in clock arithmetic, where the hours reset after reaching 12.
